Study the scenario and complete the question that follows:

Different Economic Systems

A system is a network of parts that interlock to form an overall pattern. Examples include the nervous system of the human body, the solar system, the transport system of a country and its political system. An economic system is a pattern of organisation which is aimed at solving the three central economic questions. Economic systems do not always work well, but they are often so vast and complicated that it is quite marvelous that they work at all.
